On May 16, the CJEU issued a new judgment on air passenger rights when there is a long flight delay and an airline claims extraordinary circumstances, in the case Touristic Aviation Services (C-405/23).
The CJEU's answer is not straightforward, unfortunately. There are two conditions that need to be met: the event not falling within the normal exercise of the airlines' activity and it remaining outside the airlines actual control (para 21). It refers to its previous case law on defects in refuelling systems at the airport as amounting to an extraordinary circumstance if the defect "is the result of a general failure", in that case in the refuelling system managed by the airport (para 23 - reference to case C-308/21, SATA International - Azores Airlines). The CJEU then advises the national court to check whether the shortage of staff for the baggage loading could amount to a general failure of baggage loading operations (para 24). What is missing here is an advice as to more precise parameters that would allow to lead to the demarcation of a general failure. Regarding the second requirement, whether the airline had control over the baggage loading operations could depend, per CJEU, on whether the airline could "exercise effective control over the operator of that airport" (para 27). Could this requirement potentially create a distinction between bigger and smaller airlines, as well as airlines who have their hubs at a given airport? Finally, the national court needs to examine whether the airline could have avoided this delay by taking all reasonable measures, which can e.g. mean using services of another baggage loading service provider (para 29). This again may depend on airlines' resources, leading to a further distinction between various airlines in avoiding having to pay compensation under Regulation 261/2004.
Overall, this judgment does not introduce more legal clarity by stating that a shortage of staff in luggage loading operations could constitute an extraordinary circumstance, but not being very directive on when this could occur.
